CEMENTING MACHINE.

Application led ugust 19, 1920. Serial l\o`404.,643.

To aZZ whom it may concern.'

Be it known that l, WALTER F. USGOOD, a-

citizen of the United States, and resident of Malden, county of Middlesex, Commonwealth of Massachusetts, have inventedan l'mprovement in Cementing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts in each of the several views.

This invention relates to cementing machines for applying vcement to shoe parts, such as quarters, and other more or less like uses. More particularly the invention has tov do with a double or duplex cementer adapted to apply cement simultaneously upon two material surfaces opposite one another, such as the edge-s of two quarters placed back to back. A principal object of the invention is to provide' improved inea-ns for applying and distributing' the cement upon the upper material-surface to receive the cement. A further object is to provide an improved form of cement laying rollers adapted to distribute and apply the cement moreeifectively lthan has been done withthose hitherto in use. `'llo these ends l provide means co-operative with a lower cement roll for directing and influencing the cement to How directlyv upon the upper-cement receiving surface and employ the up'- per roll as a distributing instrumentality serving to spread and press the pement evenly upon the upper material surface. ln accordance with mv invention the operative surface of the rolls is provided with dia-gonally disposed teeth or ridges adapted to direct and influence the flow of the cement over all parts of the'receiving'surfaces. The foregoing and other objects and advantages of the invention will more fully appear from the following detailed descrip-tion, and the distinctive features of novelty will be thereafter pointed out in the appended claims.

Referring to the drawings:

indicates a part of the body and cement reservoir of a cementing machine Which may be of usual and previously known type, such f or example as shown in my prior application Serial No. 273,099 filed January 25, 1919. rlhis machine body is equipped with a tubular extension or horn 11 into which extends a shaft 12 bearing at its end a lower cement applying roll 13, the major portion of which in enclosed by the horn 11 but which has an upper operative portion exposed above the horn. A combined work table and cement gauge 14 is mounted for adjustment upon a liattened top surface of the horn, this' adjustment being effected by a screw 15 equipped with a` knurled. head` 15', and determining the amount of cement which is supplied'by the roll 13, generally as set forth in my said prior appllcation. 16 indicates an arm mounted to'swing from a pivot at the rear of the machine body and bearing a rotary driven shaft 17 on the end of which is mounted an upper cement distributing and feed roll 18 as more fully shown in said prior application. As shown the arm 16 terminates some distance from the roll 18 and the projecting end portion of theshaft 17 has bearing in a block 19 borne by a stout rod orbar 20 adjusta-bly clamped in a socket of the arm 16 by means of a clamp screw 21. This block 19 fits up closely against the inner side of the roll 18 and it is equipped with an extension 19a bearing a cement deflector and roll retaining plate 22 which extends inward at the front of the roll 18, preferably tapering to a point approximately coincident With the center of the roll 18 as best seen in Fig. 2. This plate 22 fitclined for a purpose to be explained. For

may be similar to those shown in my said prior application. For applying cement to the upper material surface M, I rovide an auxiliary roll or inward extension of the lower roll 13 as indicated at 23, this roll being fixed upon the shaft 12 adjacent theV roll 13 so as to be in the nature of an inward extension thereof. This roll 23 is formed with a toothed periphery adapted to take up cement from the horn, the teeth thereof being shown however as parallel with the roll axis, while the teeth of the roll 13 are inco-operati'on with this roll 23 I provide a cement wipe-over member 24 which constitutes also a work auge as will appear. rlhis member 24 is adpistably clamped to the top of the horn 11, for this purpose having its inner end formed with an elongated slot 24a through which pass clamp screws 25. This member is formed with' a wall 24" fitting the periphery of the roll 23 and extend ing forward diagonally in the direction of roll movement, this wall hence serving to gather the cement from the roll 23 and infiuence it to move outward and toward the material. Back of this wall 24b the member 24 is formed with a pocket space or inverted valley 24 expanding outward in the direction of cement delivery, the other side of this valley being formed by a straight wall 24b which fits down closely upon the flat top of the table 14. The member 24 Yis formed at the extremity of the straight wall portion`24d with a curved notch or groove 24e which serves as an edge guide for the material, and projecting diagonally upward and forward from this groove is a prong 24, which constitutes a top guide for the material. rIhe cement flows from the inverted valley 24c upon the top-face of the work thus guided, and tending to follow the direction of travel of the work, it forms into a wave preceding the engagement of the distributing and feed roll 18. The material is held correctly alined for this cement distribution by the prong 24f in connection with the notch 24e' which co-operatively serve as guides for the material. As the material with the top surface thereof thus supplied with cement passes between the rolls 1 3 and 1 8, the upper roll 18 besides eo-operating to feed the work forward, also serves to distribute and spread the lcement evenly and uniformly upon the material. For this purpose I have found that an arrangement of teeth inclined as shown at 18, upon the p eriphery of the roll is desirable and advan' tageous, the direction of the incline of these teeth being such as to influence the cement inward or toward the edge of the material whereby an adequate and uniform coating is insured. Itis to be noted that the rolls 13,

` 18 are slightly tapered so as to present a wider opening for the work at the outer sides, than at the inner sides thereof as indicated at X, this being desirable for attaining uniformity in the spreading ofthe cementupon material such as skived quarters and the like. rl`he lower roll y13 preferably also has teeth inclined as shown for the purpose of influencing the cement inward thereof. In connection with this feature the gauge edge of the table 14 which co-operates -with the roll 13 is eut out farther toward the outer portion of the roll 13 as indicated at 26 so to permit a relatively greater quantity of cement to be taken up by the outer portion of the roll 13 to be influenced and worked inward by the diagonal teeth upon engagement with the material. The series of teeth on the rolls 13, 18 are preferably gashed or notched at intervals circumferentially of the rolls for the purpose of obtaining a better hold upon the material in feeding the same through the machine. It will be understood that suitable means (not. shown) will be provided for causing the upper roll 18 tof press upon the material to the requisite degree for feeding the material, and suitable means, shown as anv adjusting screw 27 borne by the arm 16'and engaging the top of the body 10, is provided for limiting the approach of the roll 18 to the roll 13, I am aware that. the invention may be embodied in other specific forms without departing from thespirit. or essential attributes thereof, and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive` reference being had to the appended claims rather than to the foregoing description to indica-te the scope of t-he invention.
